optical trocar
A trocar system with an integrated camera that allows direct visualization during abdominal entry.
Full Definition
An optical trocar is a specialized insertion device equipped with a transparent tip or integrated camera system that provides real-time visualization of tissue layers during initial abdominal entry. This technology allows surgeons to observe the passage through skin, subcutaneous tissue, fascia, and peritoneum under direct vision, potentially reducing the risk of major vessel or bowel injury during primary trocar insertion. Optical trocars are particularly valuable in patients with previous abdominal surgery, obesity, or known adhesions where conventional blind insertion techniques carry higher risks. The system combines the safety of open technique with the efficiency of closed trocar insertion.
Usage
Usage note: Hyphenate when used as compound adjective (optical-trocar entry).
